Problems solved by technology

When the jack is used in some fields, the stroke of the jack is not enough. Usually, a steel pipe is added at the bottom of the jack to support it, so as to increase the stroke of the jack. At present, this kind of steel pipe is directly supported at the bottom of the jack. Since the steel pipe is hollow, the force-bearing area is larger. Small, the generated pressure is high, easy to damage the jack body

Abstract

The invention discloses a steel pipe matched with a jack. The steel pipe matched with the jack comprises a steel pipe body, wherein at least one of the inner wall and the outer wall of the steel pipe body is provided with a reinforcing rib, an upper end board is fixedly connected onto the upper end of the steel pipe body, the upper end board seals an upper opening of the steel pipe body, a lower end board is fixedly connected on the lower end of the steel pipe body, the lower end board seals a lower opening of the steel pipe body, the upper end board and the steel pipe body are connected in a welding mode, and the lower end board and the steel pipe body are connected in a welding mode. The steel pipe matched with the jack is simple and reasonable in structure and is matched with the jack, the distance of the jack is increased, and the jack cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of jacks, in particular to a steel pipe for supporting the jack. Background technique [0002] The hydraulic jack, also known as the hydraulic jack, is a jack that uses a plunger or a hydraulic cylinder as a rigid lifting piece. It has a simple structure, light weight, is easy to carry, and is easy to move. When the jack is used in some fields, the stroke of the jack is not enough. Usually, a steel pipe is added at the bottom of the jack to support it, so as to increase the stroke of the jack. At present, this kind of steel pipe is directly supported at the bottom of the jack. Since the steel pipe is hollow, the force-bearing area is larger. If it is small, the pressure generated is relatively large, and it is easy to damage the jack body. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a steel pipe for supporting the jack, which has a simple a...
